.To all whom, it may concern.-

Be it known that I, HENRYy P. ROBERTS, a` citizen ofthe UnitedStates,residing at Jamestown, in the county of Chautauqua and State of NewYork, have invented certain new and useful Improvements in Wrenches,.ofwhich the following is a full and clear description, reference being hadto the accompanying draw` ings, forming part of this specification, inwhichy Figure 1k represents' a side elevation of a wrench embodying myinvention. Fig. 2 is a perspective view7 of the sliding jaw detached.

Myinvention relates to certain new and useful improvements in combinednut and pipe wrenches; and itconsists in the peculiar` constructionofthe sliding jaw anditsattached sleeve, as I shall hereinafter fullydescribe and claim. l u y I Iov enable others skilled in the art towhichmy invention appertains, I will new describe its construction andindicate the mannerin which the same is carried out. f

In the said drawings, A represents a wrench,

of usual form, having the handle a, the adjustingnut b, the fixed jawc,and the sliding sleeve d, all ofthe usual well-known construc-`Y tion,with'the exception ofthe sleeve d, which in the present case has asocket, e, formed in its sides, the said sockets terminating in inclinedWalls or stops e, the purpose of whichr and the circular sockets will behereinafter made manifest. f In the construction of many combined pipeand nut wrenches a pin or' bolt has been' passed through the sliding jaw and its attached sleeve, to serve as a pivot upon which saidjaw mightturn to more' securely grasp and hold the pipe or other cylindricalobject. The construction above mentioned is, however, objectionable inmany particulars, but especially because ofv the breaking of thepivot-pins. These difficulties. I have overcome .by constructing thesliding jaw B with'two downwardly-extending wings, f, the lower ends ofwhich are Yprovided with circular heads g,

adapted to fit the sockets e', formed in the sleeve/d. These sockets eare formed nearthe The heads are pressed intothe lsockets in such amannerthat they and' the vwings are llush with the sides of the sleeved,and ythey are permitted to rotate within the sockets to impart thenecessaryk swinging movement to the sliding jaw, whereby the serratedfaces of the xed` and sliding jaws may securely grip land hold thepipeorl other cylindrical object `6o between them, the movement of thejaw being limited by they inclined lwallsor stops before mentioned.

Thefshank C projectsfrom the center ofthe I v H fixed jaw, and thesliding jaw B has a' cenA 65 trally-disposed telongated-slot oropening,h, through which said shank passes. l The jawsj` therefore project from'both sides of the cen- .trally-arranged shankandare capable'of grasp- 5ing cylindrical or angular bodies, asvthe cir# 7o,y

cumstances require. .y A spring, D, secnredto the'sl'eeved, has' itsfree end passed within the slot or opening h and-bear's'against one ofthe Walls of the same to return the sliding jaw to its normal positionafter the pipe has been released.

kBy reason of the-above constructionI am* enabled to produce a strongcombi-nationwrench on which all balls or pivot-pins are' dispensed with,andy at the Sametime furnish 8o V means whereby the pivotal movementsofthe sliding jaw are accomplished in a positive and simple manner. Y i'f Having thus described my invention, what I claim as new, and desireto secure by Letters Y y Patent, is'- `'As an article of manufacture, acombined nut and pipe wrench consisting ofa shank having axed jaw atoneeud, projecting from disposed slot for said shank, said movablejaw.beingfopen front and rear and. provided Vwith two downwardly extendingside wings, f,' terminating at the bottom in heads g, a sleeve," d,having sockets formed in its.Y sides near' the 95 center'to receive theheads, the upper portion of said sockets dvergingr npward'ly'to form atthe front andV rear ofsaid wings walls or stops for limiting themovement of the movablejaw, and a spring for returning the jaw to itsnory 10o mal position, as herein described.V ,u l
